Mosiah 4:15

"But ye will teach them to walk in the ways of truth and soberness; ye will teach them to love one another, and to serve one another."

King Benjamin is talking to parents in this verse. He encourages us to teach our children the gospel so they do not wander down Satan's path. Teach them to love each other and to serve. The best way to teach these things is by example. If my children see me serving someone, they are more likely to serve throughout their life.
